Fixed Ladders, Any Height
OSHA Fixed Industrial Ladders Options & Configurations
Every osha fixed industrial ladder is engineered for its duty — choose the access style, then the compliance layer.
Steel Industrial Access
Q235B structural steel, hot-dip galvanized — the workhorse for plant and utility sites.
Stainless & Marine
SS304 & SS316 for chemical, food and coastal environments where corrosion rules.
Aluminum Roof Access
Lightweight, non-sparking — ideal for telecom, water treatment and roof access.
Dimensions

What an OSHA-Compliant Fixed Ladder Looks Like
An OSHA fixed ladder is a ladder attached permanently to a structure, with rungs, used for routine access in general industry — the workhorse of plant roofs, tanks, silos and mezzanines. The compliance baseline is dimensional: rungs evenly spaced 10–14 in (25–36 cm) apart, center to center; a climbing width of at least 16 in (41 cm) between rails; and clearance behind the rungs for a safe foothold.
Height decides the fall-protection requirement. Fixed ladders installed after November 19, 2018 that exceed 24 ft must be fitted with a personal fall arrest system or a ladder safety system; cages and wells are no longer accepted on new ladders. Older installations may keep their cages until the November 18, 2036 retrofit deadline — after which every ladder over 24 ft must carry a PFAS or ladder safety system.
For tall runs over 50 ft, OSHA requires landing platforms at intervals of no more than 50 ft so climbers get a rest point and a fall-protection connection changeover. Engineering those platforms into the structural calcs — and documenting compliance with a DoC, MTC 3.1 and calcs on every order — is what separates an OSHA fixed ladder from a citation risk.
Practice checklist for specifiers
- Baseline dimensions - rung pitch 10–14 in center to center, climbing width 16 in or more
- New installs over 24 ft - PFAS or ladder safety system, not a cage
- Runs over 50 ft - landing platform every 50 ft, shown in the structural calcs
- Existing cages - treat as interim only; retrofit before November 18, 2036
- Industrial application - confirm duty loads, corrosion protection and access details with the engineer
- Documentation - DoC, MTC 3.1 and structural calcs included with every order
Compliance FAQ
A permanently attached ladder with rungs used for routine industrial access; its dimensions and fall protection follow 1910.23, 1910.27 and 1910.28.
Under the current rules, 24 ft: new ladders above 24 ft need a personal fall arrest system or a ladder safety system, with no cage option.
No. Cages are not required, and since November 19, 2018 they do not count as fall protection on new ladders over 24 ft.
10–14 in (25–36 cm) center to center, evenly spaced; our standard 280 mm pitch fits inside the band with margin.
Yes — fixed ladders over 50 ft need landing platforms at intervals of no more than 50 ft, engineered into the structural calcs.
